an-Gunmen The invention relatesto window regulators and has for one of its objectsthe provision oi an improved device for automatically locking the window in its adjusted positions. B Other objects of .the invention reside in the novel features of construction and combinations and arrangements of parts as more present instance 1 is the vehicle door having the opening 2,.in' its upper portion which is adapted to be closedby the window 3 and the pocket 4 in its lower portion into which 2 the window. may enter, this window being vertically slidable in' guideways in the hinge and, locking pillars of the door. For raising -and,'loweringt have provided the pivotal li er arm 5 which is suitably connected at its outer end to the,

. WlIld OW and is rovided at its pivotal end with the externa gear'segment 6 preferably integral therewith. "This car segment meshes with the pinion 7 whic is connected Toautomaticallylock the Window in'its ad]'usted position ,the pinioir 7 is secured upon and referably made integr crank mem er 9 having the main cylindrical portion 10 in axial alignment with the pin ion and the axially ofl'set cylindrical portion or crank 11. The maincylindrical' portion .10 is journaled in the end of the housing 12 while the axially ofise'tcylindrical I rtion 45. 11 is journaled the collar 13 whic latt r,

is in turn journaled in the housing 12 in axial alignment with the main cylindrical The housing is cut away at 14 mesh with the pinion 7.

"1 5 is the handle shaftfprovided with the transverse slot 16 having outwardly'flaring fend portions with their opposite walls 1 and 17 and 18 and 18" respectively extends;

Application fled July 1.4,

3 is a cross section on the line 3'-3 the window I I es'cutcheon' a 8.1 withthe 'of relative 1924. Serial Ho. naewi and 20 are diametrically extendin ribs u on the corresponding ends of'the axially 0 set cylmdrical portion 11 and the collar 13 respectivly,.these ribs being adapted to enter the transverse slot 16.

-With this arrangement and upon rotation I of the handle 8 in either direction the walls of the transverse slot of the handle shaft 'come into contact withboth ribs to align the same thereby axially alignin the main cylindrical portion 10 and the co lar 13 and subsequently rotating both parts in unison However, with the handle 8 stationary and the lifter arm 5 exerting a force in either direction to rotatethe main cylindrical portion'10 relative to the collar 13 the axial alignment of these two parts'is destroyed and the main cylindrical portion binds in its bearing in the end of the housingto'thereby hold the window in its adjusted position. The-outwardly flaring end portions of the transverse slot 16 permit the relative rotation of the ribs 19 and 20 out of alignment and the relative rotation of the main cylindrical portion 10 and collar 13 out of axial alignment. I

The housing 12 and also thehandle and associated parts are preferably carried upon the support 21"of the door this support being apertured for the housing 12 and clamped between the annular flange 22 upon the hous-' ing andthe cylindrical flange 23 of the escutcheon-24 w ich latter flange is'threadedly engaged in b the-end of the housing. The

ISO forms a hearing or the handle'shaft 15. I I. f v I What I claim-as my invention is:
